I'm considering doing the CELTA course and then teaching in Korea for a few years.

I'm also busy with an LLB degree part time, and have around 2-3 years to go. It is very important for me to finish this, which I want to do while teaching overseas.

My question is regarding the time I'd have available for my studies, while teaching EFL. I have read on forums about contractual 30 hr. work-weeks, but teachers ending up working much longer than that, doing preparations, and other activities (meetings etc.). These aren't part of the initial contract.

I need at least 3-4 hours per day to study. Would this be possible, generally speaking, while being a TEFL teacher?

There are many things that teachers are expected to do outside their contracted teaching hours. You usually have a contract for teaching a certain amount of hours; you need to add to that: planning time, time for marking homework and tests, meetings. Added to this, newly-qualified teachers tend to spend more time preparing lessons than their experienced colleagues do. In some cases there is also travelling time. If you work for a school that has corporate clients, you might be asked to teach one lesson in one company and then to travel to another company to teach a second class. If you have this type of job, you can expect to spend a considerable amount of travelling between lessons.

Of course things vary from school to school and from country to country. Before taking on a job check on all the aspects above: how much time are you expected to spend on all these aspects (expect to get add a couple of hours to any answer you get!) and whether the activities outside of teaching are actually paid for (though this is not the norm).

I think 3 hours of studying a day on top of a new teaching job is very optimistic. You could also look out for a part-time job. Having said all that, I’ve never worked in Korea; you could also post your question in one of the open forums to get the opinion of teachers who are familiar with Korea.
